has reference, particularly, to the provision of a pouring opening forsuch cartons.

Cartons of the kind referred to have been provided, heretofore, withvarious types of pouring openings and devices, formed not only as meansintegral with the material of the cartons themselves, but also asapplied parts.

The object of the present invention is to furnish means, integral withthe material of the carton, by which a suitable pouring opening may beprovided, one feature of the invention being a preparation andarrangement of parts of the carton whereby these parts may readily bebroken away to provide the desired opening, but when broken away remainin part attached to the carton so that they may be returned to theirinitial position to close the opening, when desired. Moreover, suchclosing movement of the parts is limited, whereby their projectionwithin the carton is prevented, thus forming, in eifect, a removable, orhinged, closure and stopper for the pouring opening.

The invention contemplates a carton of the customary folded blank type,having a body provided with a plurality of flaps adapted to be foldedone upon another and thus secured and sealed in overlapping juxtaposedarrangement to close the carton end, certain of such flaps furnishedwith partially severed portions including hingeforming parts joiningthese portions to the flaps; the partially severednportions subject tobeing torn or broken away so as to hinge upon their hinge-forming parts,to thus form a pouring opening which they are adapted to close, whendesired,

all as will be explained more fully hereinafter and finally claimed.

In the accompanying drawings illustrating the invention, in the severalfigures of which like parts are similarly designated, Figure 1 shows theblank from which the carton of the invention is formed.

Fig. 2 is an enlarged perspective view showing ing the blank folded toproduce the carton, one end, which may be considered-the bottom, beingclosed, and the other end, which may be considered the top or pouringend, having the flaps by which it is normally closed in unfolded or opencondition.

Fig. 3 is a fragmentary perspective view similar to Fig. 2, but showingthe flaps of the narrow sides of the carton folded in at the top orpouring end of the carton.

Fig. 4 is a View similar to Fig. 3, but showing one of the flaps of abroad side of the carton folded in upon and secured to the flaps of thenarrow 5 sides.

Fig. 5 is a view similar to Fig. 4 but showing the pouring end of thecarton completely closed and sealed.

Fig. 6 is a perspective view of the carton with 10 the partially severedportions broken away and' tilted back upon their hinge-forming parts todisclose the pouring opening.

Fig. 7 is a section taken substantially on the line 1-1 'of Fig. 6, butshowing the parts en- 15 larged, and

Fig. 8 is a sectional view similar to that of Fig.

7, showing the pouring opening closed.

Referring to Fig. 1,'it will be seen that the blank from which thecarton of the invention is 20 formed comprises a piece of ordinaryboxboard, pasteboard, cardboard, or other suitable cartonforming stock,appropriately cut and scored to provide broad sides I and 2 and narrowsides 3 and 4 for the carton, and a securing strip 5 at- 25 tached tothe broad side I.

The broad sides I and 2 are provided with flaps 6 and 1, respectively,and the narrow sides 3 and 4 are provided with flaps 8 and 9,respectively, all of which flaps when folded into overlapping 30engagement, and secured by suitable adhesive, as is customary, provide aclosed and sealed end or bottom for the carton.

The opposite ends of the broad sides I and 2 are provided with flaps l0and II, respective- 35 ly, and the opposite ends of the narrow sides 3and 4 are provided with flaps l2 and I3, respectively, which, whenfolded into overlapping juxtaposed engagement and secured by suitableadhesive, as will be explained more fully hereinafter, 40 provide asealed top or pouring end for the carton.

The several sides and flaps referred to are delimited by the edges ofthe blank and by suitable cuts a and scorings b and c, as will beapparent from an inspection of Fig. 1.

The flap l2 of the narrow side 3 is provided with an opening [4, and theflaps I0 and II of the broad sides I and 2, respectively, are providedwith portions l5 and i6, respectively, defined by slits- H, but joinedto the flaps by hinge-forming parts [8 and by tabs l9, which tabs areonly partially severed by spaced slits, as indicated at 20, so asnormally to} maintain the portions l5 and I6 intact-with the flaps I0and II, respectively.

However, being frangible by virtue of their partially severed condition,the tabs I9 will enable the portions I5 and I6 to be broken away fromthe flaps except for their hinge-forming parts I8 as will later appear.It will be noted that the partially severed portion I6 is of greaterarea than the similar portion I5, for a purpose to be more fullydescribed.

Referring now to Figs. 2, 3, 4, and 5, it will be seen that the cartonis formed by folding the blank upon its vertical scorings b andattaching the strip 5 to the inner face of the narrow side 4 adjacent toits free edge. Then the flaps 8, 9, 6, and 7 are folded in, preferablyin the order named, and secured together in overlapping, sealedengagement preferably by a suitable adhesive.

After the carton has been filled with the commodity to be marketed in itthe top or pouring end is closed by folding in the flaps I2 and I 3, andI and II in the order named these flaps all being secured together inoverlapping sealed engagement and in juxtaposed relation by means ofsuitable adhesive.

Although in the foregoing description the bottom end of the carton hasbeen referred to as the end first closed and sealed the top or pouringend may first be closed, and the bottom end closed and sealed after thecarton is filled with the commodity to be marketed. In fact, this latteris the usual practice, the reversal of the operation, as described,being merely for the purpose of a ready accommodation of the descriptionto the showing contained in thedrawings.

with the endflaps 10, 11, 12, and 13 folded in and secured as described,and as shown particularly in Fig. 5, it will be apparent that theopening I4 in the flap I2 underlies the partially severed portions I andI6 of the flaps I0 and II, respectively, and thus, when the tabs I9 arebroken away at 20, and are disengaged from the adhering area of the flapI2, the portions I5 and I6, which are joined by adhesive, may be swungupwardly, as a unit, upon their hinge-forming parts I8, as illustratedin Figs. 6 and 7, thereby providing a pouring opening d in combinationwith the opening II formedin the flap I2, and through this opening thecontents of the carton may be poured out.

As hereinbefore mentioned, it is to be noted that the area of thepartially severed portion I6 is greater than that of its complement I5and, consequently, the slits at I! and 20 in the two flaps I 0 and II donot register and the material of one flap seals the slits in the otherto thus provide a perfectly tight or sealed closure. Moreover, theportion I 6 being larger than thevportion I5, it provides a rim oroffstanding flange 2| around the portion I5, and this rim or flangefunctions, by contact with the underlying portion of the flap ID toprevent the united portions I5 and I6 from being projected within thecarton when these united portions are returned to their initialposition, as illustrated in Fig. 8. This function is augmented by theunited tabs I 9 which bear against the exposed portion of the flap I2.

Thus the united severed portions I5 and I6 form in effect a hingedstopper and closure for the pouring opening, and provide an effectiveseal for the carton. 1

It will be apparent, furthermore, that due to the relatively rough orragged edges of the tabs I9, formed by their broken-away portions, anappreciable frictional engagement will be formed between these edges andthe adjacent complemental edges of the flaps I0 and I I when thecombined stopper and closure is returned to its init al position, tothus hold it in such position and guard against accidental spilling ofthe contents through the pouring opening.

It will be obvious, from the foregoing, that in order to open thepackage for pouring of its con- 5 tents from the pouring opening, it ismerely necessary to press upwardly upon the united exposed edges of thetabs I 9. This will cause the breaking away of these partially severedtabs and enable the portions I5 and I6 to be swung upwardly 10 upontheir hinge-forming parts I8.

Various changes and modifications are contemplated as within the spiritof the invention and the scope of the following claims.

What I claim is:

1. In a pouring carton, a body having an end composed of a plurality offlaps folded into overlapping relationship, two of said flaps arrangedin juxtaposition, each of said last-named flaps provided with apartially severed portion includ- 2o ing a tab extending to the edge ofits respective flap, and hinge-forming parts joining said partiallysevered portions with their respective flaps, the aforesaid tabs of saidpartially severed portions being frangible to permit tilting of saidportions upon said hinge-forming parts to provide a pouring opening atthe end of said carton.
